Question

（我知道Opencart的早期版本对此有疑问，但我使用的是3.0.3.2。当我更改代码以在优化搜索中合并图像时，出现了PHP错误。（链接的计算机图像只是占位符。）

我尝试更改catalog / controller / product / category.php中的代码

 if ($category_info['image']) {
            $data['thumb'] = $this->model_tool_image->resize($category_info['image'], $this->config->get('theme_' . $this->config->get('config_theme') . '_image_category_width'), $this->config->get('theme_' . $this->config->get('config_theme') . '_image_category_height'));
        } else {
            $data['thumb'] = '';
        }

        $data['description'] = html_entity_decode($category_info['description'], ENT_QUOTES, 'UTF-8');
        $data['compare'] = $this->url->link('product/compare');

        $url = '';

        if (isset($this->request->get['filter'])) {
            $url .= '&filter=' . $this->request->get['filter'];
        }

        if (isset($this->request->get['sort'])) {
            $url .= '&sort=' . $this->request->get['sort'];
        }

        if (isset($this->request->get['order'])) {
            $url .= '&order=' . $this->request->get['order'];
        }

        if (isset($this->request->get['limit'])) {
            $url .= '&limit=' . $this->request->get['limit'];
        }


        $product_total = $this->model_catalog_product->getTotalProducts($filter_data);

        $results = $this->model_catalog_product->getProducts($filter_data);

我在第135行和第137行（上面的代码的最后几行）出现未定义的变量错误。

Answer 1

我认为该错误与变量$filter_data

有关

应在这两行之前声明

$filter_data = array(   
            'filter_category_id' => $category_id,   
            'filter_sub_category' => $this->config->get('config_product_category') ? true : false,  
            'filter_filter' => $filter, 
            'sort' => $sort,    
            'order' => $order,  
            'start' => ($page - 1) * $limit,    
            'limit' => $limit
);
